About Tool steels for hot work
Tool steels for hot work are alloy steels designed for tooling that operates in contact with heated metal. They are characterised by hot hardness, wear resistance, toughness and resistance to thermal fatigue, making them suitable for dies, moulds, punches and other forging, extrusion and die-casting tools.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Predicted transformation temperatures
Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni.
Physical & mechanical properties
An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.
Similar grades — and why
Selection rule, stated so you can disagree with it: same number class 1.2, a shared category, and a published range for Cr / Co that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
